How to reset the root password of VMware ESXi 4.1 Embedded edition

I would like to take this chance to say Thank you to Bernhard Bock (bernhard's blog - http://www.bock.nu/blog) to posting this solution to us.

I just modify little bit to fit for "VMware Embedded edition"

The tools is GRML (grml.org) - Debian-based Live CD made for system administrators and users who prefer text tools.

The following steps which is I did for reset password:

The solution at the following: (Only apply for DELL VMware Embedded edition, for the standard/Installer edition, we need to change the local.tgz which is containing by states.tgz)

First of all, we need to boot your ESXi server with a "GRML"
mount /mnt/Hypervisor1
cd /tmp
tar xzf /mnt/Hypervisor1/local.tgz
vi etc/shadow (Remove remove the hash altogether (everything between the first and the second colon))
mv /mnt/Hypervisor1/local.tgz /mnt/Hypervisor1/local.tgz.bak
tar czf local.tgz etc
mv local.tgz /mnt/Hypervisor1/

Since there are two "volume" of Hypervisor, we need to repeat those step at Hypervisor2

mount /mnt/Hypervisor2
cd /tmp
tar xzf /mnt/Hypervisor2/local.tgz
vi etc/shadow (Remove remove the hash altogether (everything between the first and the second colon))
mv /mnt/Hypervisor2/local.tgz /mnt/Hypervisor2/local.tgz.bak
tar czf local.tgz etc
mv local.tgz /mnt/Hypervisor2/

If your Hyper-V remote management is in a workgroup environment and it work well. But one day, you receive a error message “Hyper-v rpc server unavailable” when you try to use a Server Manager to remote access it.

(Printer Server) The specified location does not contain the driver for the requested processor architecture

When you try to install a 32bits printer driver to the additional driver of a 64bits Windows Server 2008/R2. You got the following errors:

The specified location does not contain the driver for the requested processor architecture

Solution:
Install the same type of the 32bits and 64bits driver of the printer.

e.g. You need to install a HP LaserJet 5200 on a 64bits Windows Server 2008/R2
You need to download the same type of the 32bits and 64bits.

If you want to install the PCL6, you need to install the following two drivers.
HP LaserJet 5200 PCL 6 Driver and HP LaserJet 5200 PCL6 64-bit Driver
Both of the printer drivers (32bits and 64bits) are PCL6.

You cannot install one is PCL 6 and the other is PCL5 or PS....

A program cannot set default issue to open in Win7 (File Association)

It is because this software pointing to isn't registered correctly. (Since in Windows 7 all 32bits software will be in "Program Files (x86)", instead of "Program Files")

The solution is change the follow registry in "Computer\HKEY_CLASSES_ROOT\Applications\"

[HKEY_CLASSES_ROOT\Applications\ABC.exe\shell\open\command]
@="\"C:\\Program Files (x86)\\Innov\\ABC.exe\" \"%1\""

And then go through the "regular" process to associate a program with an extension.
